Patent GB-1115567-A (GB)
Title: Telephone exchange
IPC: H04Q3/00
Filed: 1967-05-19
Abstract: 1,115,567. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 19 May, 1967 [20 May, 1966], No. 23397/67. Addition to 1,112,746. Heading H4K. In a multi-stage reed-relay switching network having a plurality of cross-point matrices per stage, each matrix has associated therewith a marking relay and each stage has associated therewith a set of further marking relays, there being one of the latter for all like-numbered rows in each of the matrices of the stage and the contacts of both types of marking relay being connected in series with the energizing coils of all the cross-point relays in the stage. During route finding, one matrix in each stage is selected and the corresponding matrix marking relays and the required row marking relays are operated and thereafter operating potentials are applied to the relevant inlet and outlet of the network whereby those cross-point relays in the (effectively) single path between the inlet and outlet come up and hold via their own contacts. Trunking.-The network shown is conventional in that each matrix in one stage has access to all the matrices in a following stage via one link only. It is suggested however that there may be more than one link between successive matrices, the row marking relays (see below) then being operative on a lock-out basis. Particular description.-The method of route searching is not disclosed but it results in the selection of one matrix in each stage and the consequent operation of their marking relays e.g. HA1, HB2, HC1. Contact ha15 of relay HA1 thus applies earth to the so-called setting wires e.g. eb2 of all the links extending from matrix KVA1 in stage A. Since HB2 in matrix KVB2 is operative, the incoming earth on eb2 brings up row marking relay BB1 and an earth (from contact hb25) is extended over the setting wires, e.g. ecn of the BC links. In matrix KVC1, HC1 is operative and row marking relay CB2 comes-up to the incoming earth on ecn. A control circuit (not shown) responds to the operated marking relays by applying +U over contact k to " inlet " wire cd1 and earth to marking wire ma1 which corresponds to row 1 in each of the first (A) stage matrices. Consequently diode decoupled cross-point relays II in matrix KVC1, I in matrix KVB2 and III in matrix KVA1 operate in series substantially simultaneously and they hold via their make contacts 1 in series with the so-called seizing wires sb2 and sell of the AB and BC links. The control circuit substitutes holding potentials of earth and -U2 to the " inlet " feedbridge (cd1) and " outlet " line circuit (ca1 and then releases the marking relays. The first stage matrices may be constructed in exactly the same way as those in other stages, the method of applying operating potential being adjusted accordingly. The control circuit may be used instead of the setting wires for controlling the operation of the row marking relays.

Title: Improvements in apparatus for feeding and collating cigarettes and other small articles
IPC: B65B19/10
Filed: 1922-09-02
Abstract: 207,281. Molins, W. E. Sept. 2, 1922. Packeting cigarettes and other small articles in receptacles.- Relates to apparatus for assembling cigarettes and other small articles in batches for delivery to packeting machines. The cigarettes are delivered' by a rotary fluted drum operating in a hopper to a plate or table, along which they are moved in batches by projections on an endless belt conveyer arranged above the table. At the delivery end of the plate, the cigarettes are removed at right-angles to the previous feed by a transfer conveyer such as is described in Specification 13956/15. The cigarettes are fed from a hopper by a fluted drum 2 from which they are removed by the prongs 5 of a plate 6 projecting into peripheral grooves 4. Members 9, on an endless chain 7 travelling at a higher speed than the drum, gather the cigarettes into groups D and pass them along the plates 6 to the delivery end. The cigarettes are then in position on plates 13, 14 from which they are removed at right angles by a plunger to a packeting machine, the web of the plunger passing through the slot 14<a>. When a large number of cigarettes are to be fed, fingers 20 may be fitted to the end sprocket-wheel of the conveyer chain, and so geared as to sweep about half of the intended group along the plate 6 in advance of the conveyer piece 9. Quadrants 12 on the sprocket-wheel of the conveyer form a continuation of the parts of the pieces 9 and hold the cigarettes in position on the bridge. When two or more superposed rows of cigarettes are desired, the apparatus may be multiplied accordingly. According to the Provisional Specification, when oval cigarettes are to be fed the prongs on the carrying plate 6 may be made sufficiently long to extend beneath the hold-back roller 3 and may be shaped so as to lift the cigarettes slightly from the flutes when passing under the roller, in order to prevent surplus cigarettes from being fed and to cause all the cigarettes to be turned in the same diraction.

Abstract: 1,188,385. Valves. VENDO CO. 24 May, 1967, No. 24041/67. Heading F2V. A flow control valve compensating for pressure and viscosity variations in the fluid to pass a predetermined amount thereof per unit time has an integral plunger-piston unit 115, 116 controlling flow from an inlet 124 to an outlet 128 by relative movement between the plunger annular groove 130 and housing ports 132. The piston has a short orifice 126, the pressure drop across which biases the piston downwards against the adjustable loading of spring 122. A tube 118 with a restricted bore screwed into the central passage 117 of the plunger-piston unit compensates for viscosity by applying an upward force on the piston due to frictional drag. The valve 130, 132 is thus closed on inlet pressure rise and opened on viscosity side. Fluid at the opposite ends of the plunger-piston unit damp the movements thereof to prevent "flutter". In a modification the tube 118 is dispensed with.
